WARNING - Risk of explosion
Keep lit cigarettes and all other flames or sparks away from the battery.
The battery contains hydrogen -- a highly combustible gas which will explode if it comes in contact with a flame or spark.
Keep batteries out of the reach of children because batteries contain highly corrosive SULFURIC ACID and electrolytes. Do not allow battery acid to contact your skin, eyes, clothing or paint finish.
Wear eye protection when charging or working near a battery. Always provide ventilation when working in an enclosed space.
Always read the following instructions carefully when handling a battery.
If any electrolyte gets into your eyes, flush your eyes with clean water for at least 15 minutes and get immediate medical attention. If electrolyte gets on your skin, thoroughly wash the contacted area. If you feel pain or burning sensation, get medical attention immediately.
An inappropriately disposed battery can be harmful to the environment and human health. Dispose the battery according to your local law(s) or regulation.
Never attempt to recharge the battery when the battery cables are connected.
WARNING - Risk of electrocution
Never touch the electrical ignition system while the vehicle is running. This system works with high voltage which can "zap" you.
✽ NOTICE
If you connect unauthorized electronic devices to the battery, the battery may be discharged. Never use unauthorized devices.
